Groundwater Control during construction of the USSTRATCOM Command and Control Facility

Project Name: Groundwater Control during construction of the USSTRATCOM Command and Control Facility

Project Location: Nebraska

Owner: Offutt AFB

GC: Kiewit-Phelps, JV

Engineer: US Army Corps of Engineers, Omaha District

Project Revenue: $250,000.00

Project Start and End Date: 2012 to 2014

 

The Challenge:

The USSTRATCOM Command and Control Complex is a 1 million square foot facility that is 70 ft. below ground surface. The structure used concrete placed walls that were installed to bedrock to create a water tight structure.

The Solution:

To dewater the excavation to the required drawdown, Griffin used 6 wells inside the structure with

2400 LF of discharge pipe. The water inside the structure required treatment. Griffin mobilized a

temporary water treatment system to treat the water inside the structure that had high levels of

suspended solids (TSS) and high pH levels.

The Griffin Difference

Griffin provided dedicated operation and maintenance personnel for both the deep foundation dewatering and the water treatment system to keep the multiple systems operational during the complex construction sequence.

Regular monitoring and preventive maintenance measures were conducted on both systems to ensure optimal system performance for the duration of the project.
